Summary
A three-stage nonlinear-fiber design generated a 50-gigahertz-spaced optical frequency comb.
The modeled chain used four-wave mixing, pulse compression and a second nonlinear fiber. At the reported power and 0.2-kilometer first stage, it produced about 20 lines with plus or minus 4.785-decibel flatness.
